Hinweise

Der Accept -Header ist eine Zeichenfolge mit durch Leerzeichen getrennten Multipurpose Internet Mail Extensions (MIME)-Typnamen image/jpeg(z. b.), die die MIME-Typen angeben, die der Client in einer Antwort akzeptieren und verarbeiten soll.The Accept header is a string of space-separated Multipurpose Internet Mail Extensions (MIME) type names (for example, image/jpeg), which indicate the MIME types that the client is prepared to accept and process in a response. Der */* Eintrag gibt an, dass der Client einen beliebigen MIME-Typ akzeptiert.The */* entry indicates that the client accepts any MIME type. Eine ausführliche Beschreibung des Accept Headers finden Sie unter RFC 2616, verfügbar unter. https://www.rfc-editor.orgFor a detailed description of the Accept header, see RFC 2616, available at https://www.rfc-editor.org.
